This is the desktop digital telescope that displays a magnified view on a computer monitor, so a roomful of young astronomers can simultaneously enjoy astral observation. A digital camera fits over a special eyepiece and connects to a computer’s USB port, enabling images or video of Orion, Ursa Major, or any celestial body seen through the telescope to be captured and saved.
The telescope has a 400mm focal length with four eyepieces (15X, 20X, 25X, and 35X) that can be changed simply by rotating the central turret. The telescope can be detached from the computer for traditional solo observation and the camera attaches to a separate stand to act as a web camera with 640×480 resolution.
This working Heron steam engine is propelled by the same pneumatic principles that powered Heron of Alexandria’s original steam turbine in the first century AD. A precursor to the jet engine, Heron’s steam turbine was the first of its kind to extract thermal energy from pressurized steam and convert it into rotary motion.
The desktop steam turbine is powered by an alcohol burner that heats a sphere boiler holding 2/3 oz. of water, evoking the metal cauldron that heated Heron’s original aeolipile. When steam is generated, it is expelled through two nozzles on the sphere pointing in opposite directions, generating thrust that rotates the sphere on its axis up to 2,500 rpm.
Miguel Soto bought a sandwich at a deli and walked home. While on his way, he was shot twice. But Soto didn’t let that problem distract him from having his meal:

Recent evidence shows that people who thrive at night have higher IQs. Early risers beg to differ..Are you the type who stays up late to finish your work, or do you get up early to make a fresh start on the day?
If it’s the former, you may be pleased to learn new research has found that those with higher IQs tend to be nocturnal night-owls. But if it’s the latter, you might have good reason to distrust the claim. Here’s an instant guide:
The Chinese are going through an industrial revolution, building factories and public works projects at breakneck speeds. They also like to set construction speed records it appears. Behold the incredible time lapse construction of the 15 story Ark Hotel.
The 15 floor superstructure was completed in just 46 hours and the exterior of the hotel was completed in an additional 90 hours. Believe it or not, the hotel is rated level 9 Earthquake Resistance. Kudos to the construction teams, it is a true technological marvel to say the least.
